my pressure was 52p @ idle and 43p @ wot so I changed my regulator spring to the longer blue one. Someone had done the bb mod so O took that out and put in the new spring and had the same pressure 52p and 43p so I put the bb back in with the new spring and was at 70p @ idle and 65p @ WOT
just where I wanted it. Now every day it has come down a little at a time. The day after the mod it was at 68p @ idle the next day 65p @ idle and 58p @ WOT now today it is at 62-63p @ idle and 56-58p WOT WHAT GIVES!!
I have no leaks. The fuel pump was replaced 2yr ago and also has a summit raceing pusher pump to give extra pressure and all works. Any help please. The only change is the weather has gotten colder.
